Filed. dan. 18, 1961, Ser. No. 83,489 3 Claims. (Cl. 15-119) The object of this invention is to devise novel extracting mechanism for mops of the spaghetti type in which the strands have an absorbent core and `a plastic tube containing the core.

A further object is to devise a novel carrier having loop forming extractor members connected with it in a novel manner so that in their forward passage over the mop head they will be in the `form of a substantially closed loop for the extracting movement, and during their rearward movement over the mop head they will swing outwardly to expand the loop and `form a `gap of sutl'icient width to permit them to drop downwardly over the handle into closed loop condition in alignment with the mop head ready for the next extracting operation.

With the foregoing and other objects in view as will hereinafter clearly appear, out invention comprehends a novel mop with novel extracting mechanism which provides a closed loop for the extracting operation and an expanded loop to permit the extracting members to pass over the handle into aligned position with the mop head.

For the purpose of illustrating the invention, we have shown in the accompanying drawings preferred embodiments of it which we have found in practice to give satisyfactory and reliable results. It is, however, to be understood that the various instrumentalities of which the invention consists can be Ivariously arranged and organized, and we do not therefore desire to be limited except by the scope of the appended claims to the exact arrangement and organization of these instrumentalities as herein set forth.

Referring to the drawings:

In the extracting or wringing operation the operator holds a mop handle in one hand and the sleeve in his other hand, with the extractor and its rod above the mop handle and with the mop handle and its head in a downwardly inclined position.

The mop has a handle 1 to which a mop head 2 is detachably connected. The forward portion of the handle is in the form of a rectangular bar `4- secured to ther body portion of the mop handle in any desired manner.

3,084,366 Patented Apr. 9, 1963 ice The bar -4 has at its forward end a slot 5 opening through its top lface to receive a cross member 6 forming a part of the mop head. A cup 7 is slidable on the bar and when moved forwardly over the rear end of the mop head retains the mop head and bar in assembled condition. This manner of interlocking bar and mop head is claimed in a copending application, Serial No. 29,513, tiled May 16, 1960, now Patent No. 3,040,355.

The extractor mechanism has a carrier 18 having a slot 9 opening through its sides and bottom, and holes 10 open into the slot and pivotally support the upper bent ends of loop forming extractor members 11 and I2 which are guided in the carrier slot and have their free ends normally overlapping each other. The upper wall of the slot limits upward swinging movement of the members and the rear wall 14 of the slot limits rearward movement of the members.

The carrier 8 in FIGURES 1 to 5 has the front end of a carrier operating rod 15 permanently fixed to it, yfor example by welding, and this rod passes through and is guided in an opening in a `guide 16 mounted on the mop handle. The rod has a desired clearance in the guide opening to provide for the proper clearance of the car- Iier with the mop head during the rearward movement of the carrier. The rear end of the rod is bent downwardly and pivoted at 17 to a sleeve 18 slidable on the mop handle. 'Ihe sleeve has a projection 19 extending into a longitudinal Igroove Ztl in the mop handle. A stop 20 on the handle limits rearward movement of the sleeve on the handle.

In FIGURES l to 5, both loop forming members are pivotally mounted on their carrier, while in FIGURES 6 to 8 only one loop forming member is pivotally mounted and the other is 4iixed at its upper end to the carrier. Loop forming member 21 is xed on carrier 22 and member 23 is pivoted on the carrier in the hole 24. Carrier 22 `is pivoted at 25 to operating rod 26.

'Ihe iixed member 21 is shorter than member 23, and the pivotal point of member 23 is above that of 21.

In the embodiment of FIGURE `9, the carrier 27 has loop forming extractor members 29 and 30 having their rupper ends bent at an angle and pivoted in holes 31. The carrier 27 is pivotally mounted on its operating rod 32.

In the embodiment of FIGURE 10, the carrier 33 has loop forming extractor members 34 and 35, the member 34 being iixed t-o the carrier and the member 35 having its upper end bent and pivoted in the same manner as the member 30 of FIGURE 9 or 23 of FIGURE 7. 'Ihe operating rod 36 is pivoted at 37 to the carrier 33. The upper ends of the pivoted member and the fixed member extend more :like a straight line so that the loop formed by the members assumes more the form of a V.

If the parts are in the position shown in FIGURES 1 and 2 `and in full lines in FIGURE 37 and the carrier is moved forwardly by its rod and sleeve, the extracting members pass over the strands to extract the water therefrom. On the rearward movement of the carrier, the -mop head swings the members upwardly and forwardly thus expanding the loop to form a -gap between the free ends of the members. After passing over the mop head, the members are free to move inwardly, pass downwardly over the handle and close the gap with the loop in `alignment with the mop head, ready for the next extracting movement.

The operations of the other embodiments are the same as that described except that if one loop yforming member is permanently fixed to the carrier the carrier should be preferably pivoted to its operating rod.

If both members are pivoted to their carrier, the carrier may be permanently connected with the rod or pivoted to the rod to permit the upward movement of the carrier on its return movement. When the carrier is pivoted to its rod, the walls of the slot limit its rearward swing to preferably a substantially vertical position although this swing may be greater if desired without interfering with the operation.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

l. A mop comprising a mop handle and mop head connected with the mop handle, in combination with a earrier, a rod connected at its forward end 4with said Carrier,`

loops having portions movably guided in said slot, said loops being laterally deected at the upper end and pivotally connected with said carrier and being free to swing outwardly into open position and inwardly into closed position, said loops when the carrier is moved rearwardly ride over the mop head and swing outwardly to permit the loops, when in their rearrnost position, to pass over the mop handle into longitudinal alignment with the mop head for `the forward extracting movement of the loops.

2. The construction deined in claim l wherein the carrier is pivotally mounted on the rod.

3. The construction dened in claim l wherein the loops overlap each other when they are in their closed position.
